Abstract
A perforating device for the representation of letters and numbers with adjustable perforating gearwork and with a drive for the perforating gears for rapid shifting of letters and numbers and to a process for setting perforating devices. The perforating device provides for the representation of letters and numbers. The device is constructed compactly and assures a simple manipulation and an exact setting of the letters and numbers, as well as an uncomplicated electronic control. Drives for perforating gears are arranged in recesses arranged on the periphery of perforating gear uptake.
Claims13
A perforating device for representation of letters, symbols, and/or numbers, comprising:
- an adjustable gearwork including perforating gears;
- electronically controlled drives provided for the shifting said perforating gears of said adjustable gearwork;
- and
- a perforating gear uptake having a periphery with recesses for said perforating gears, said electronically controlled drives being introduced into said recesses, said recesses extending one of radially and axis-parallelly on said periphery of said perforating gear uptake or arranged axially displaced by at least one gear width (d) on said periphery of said perforating gear uptake.
A process for perforating for representation of letters, symbols, and/or numbers, comprising the steps of:
- providing an adjustable gearwork including perforating gears;
- providing electronically controlled drives;
- shifting said perforating gears of said adjustable gearwork with said drives and introducing said perforating gears into a programmed position for carrying out a perforation at a predetermined time point whereby said perforating gears of said adjustable gearwork provide perforations for the representation of letters, symbols, and/or numbers;
- providing a perforating gear uptake having a periphery with recesses for said perforating gears;
- and
- introducing said electronically controlled drives into said recesses, said recesses extending one of radially and axis-parallelly on said periphery of said perforating gear uptake or arranged axially displaced by at least one gear width (d) on said periphery of said perforating gear uptake.
